Watermelon Pizza with Radish, Red Onion & Lime

Written by Dietitian & Mom: Elis Halenko

A fresh and fun summer snack that’s hydrating, gut-friendly, and totally blood-sugar conscious.

When summer hits, all I want are simple, cooling snacks that feel like a treat—but at the same time still pack some nutrition. Enter: Watermelon Pizza.

It’s crunchy, juicy, refreshing, and topped with vibrant veggies and herbs for a savory twist. Unlike the classic sweet version, this is not your kid’s watermelon sprinkled with chocolate chips (though we love that too). Instead, this version is balanced, beautiful, and makes the perfect snack board for patio lunches, playdates, or solo mom breaks in the sunshine.
